Polyaspartic Waterproof Coating: Superior Solution for Exterior WallsKnowledge19 Nov, 2024The exterior wall transparent polyaspartic waterproof coating is made by reacting high-purity polyaspartic resin with isocyanate prepolymer. This creates a durable and transparent waterproof layer. It adheres directly to substrates like wall tiles, resisting peeling, surface powdering, or blister formation. This product provides long-lasting waterproof protection, excellent weather resistance, strong adhesion, flexibility, abrasion resistance, crack resistance, and eco-friendliness. It effectively prevents water seepage, ensuring a reliable and extended service life for wall surfaces.

Common Issues in Waterproof Coating ApplicationKnowledge15 Nov, 2024Polyaspartic elastomers are a novel, slow-reacting, high-performance, and non-yellowing aliphatic coating material that has recently emerged in the polyurea industry. Known as the third generation of polyurea, Feiyang's polyaspartic resin is a solvent-free, transparent liquid modified with aliphatic secondary diamines (terminal amino group polyether) and is also called PAE resin. It can react directly with NCO-containing triisocyanates (either aromatic or aliphatic) or blend with hydroxyl-containing polyester and acrylate resins before reacting with NCO isocyanates to form SPUA polyurethane elastomer coatings.
